Be it known that I, yBnNJsinrn Bananen of thel city, county, and State ot'- New York, have invented a new and improved Quarta-Crusher and'Pulverizer; and I do hereby declare that the following isa full, clear, and

:exact descriptionthereoi, 'which will enable others skilled in the artjitomake and use the same, ,reference being had to the-accompanyingldrwings forming a part of this specification. v

This invention relates to a new and improved apparat`m-a or device for crushing, and pulverizingquarta, and

it consists of a series of crnsher s, arrenged on'the toggle principle, and provided at onev end'with elastic or yielding bearings, whereby the crushers are .allowed to yield or give in caseLof coming 'in contact vwith anyforeign substancesnch as spikes or other metal. articles, and the crushers prevented from being injured orv broken thereby. Y The invention further consists in a novel construction-of pressure-rollersfor pulveriziug the crushed quartz,

whereby therollers'are allowed to'yield or give vto admit of any hard foreign substance escaping between them/1v without injuring the rollers-or subjecting the same totany undue strain.`

Ar'epresents the frame of the machine, which may b .oonstructedfin 'any proper manner to support the worlrihgparts. A v A A' On 4the top of this frame Athere is secured a boa, B, which is divided into' three compartments by partitionplntes,'a, and in each o f these compartments a toggle, C, is placed.l `".lhese toggles, at one end, are connected by'v t pivots b to shoesv C', the lower ends of which are all fitted loosely o n a shaft, D, the latter passingvv transversely through one end of the box B. The opposite ends of the toggles are' connected by pivots, c, to slides, E, between which andthe end of the box B, 'springs F, of India rubber or other suitable material, are placed, and within each compartment there are secured two eccentrics, d ,b'y turning or adjusting which the slides may be pressed moreor lessback, andthe play or movementA of 4the slides E regulated as occasiony may require.'

In fig. 2 only one slide, E, is shown, but in practice itis designed to have all the togglesattache'd to them, 'a slide to each toggle.'- if The shoes C' areoperated by raising the toggle's, which is done byfm'e'ans'of cams G on a shaft H, thel latter being turned by 'gears c f from the shaftg `of one'of the pressure-rollers hereinafter described.

I isa chute, which leads from the shoes C downto the pressuren'ollersJ'J,'.andconducts the'crabkcd.-

quartz fromthe shoes to eaid'frollers. The quartz is cracked between the shoes and the end ofthe box B,'the cracking'being eected when the central portions of the toggles vare forcedl upward under 'the' actionV of the cams G; As thetbggles'arefrelievjed from the prominent portion'sot" the'cains, they drop by their own gravity,v and ure raised again by the prominent portions of the cams as they again comefaround.- Thel shoes are prevented from being injured by any hard-foreign substance .passing down between= them and the end of bonB, by the yielding of the slides E, the'springs F admitting of -this. fl'he'pres'snre'of the shoes Clv against the endet' box B may be regulated as desired by adjusting the eccentrica The pressure-roller J may be of 4ordinary construction', and the bearing, 7l, of 'itsshaft, j, are not 'lxed,

lthe bearings and plates k, as shown clearly in 2. t

The bearingsh of the otherrolilerJ are similarly arranged, j representing thesprings and 7c the plates (see dg?. 8.)vv The position-of the plates lc k' of both rollers may be' adjusted by set-screws o. I

The roller J is of practical construction. Its shaft, g, has two collars, qg, firmly secured upon it,'and India-rubber heads, r r, are placed upon the shaft, and bear against the collars q q,-and loose collars, o o, are

" but allowed to slide a certain distance, and they bear:1 against rubber springs, j, which are interposed between I remi 2 placed upon the shaft g, et, the opposite sidesof the heads,-l thefcollerso beingpressed np aga-insb the rubber heads r by means of nuts t. v

By this nrrangement, thende-rubber heads r rmay be lexpended to iii;l tightly within n hollow cylinder, u,

i .'wfhich forms the periphery Aof the yroller J.- "This ,willfbe fully nnd'erstood by referring to iig'. 4. The rubber heads, it 'will be seen, odmifgof the cylinder u, Which is the periphery ofthe vroller J', yielding or'giving in case of any herd foreign 'snbstoncefsuch forizisizanee",` as pieces of iron,- pcssing between them.

This yielding of Athe roller J', in connection wfh the yielding of the ,bearings in which rtheir shafts nre'iitted, will effectually preventrthe ,rollers'or n ny of their Vports being broken, strained, or injured by the passogevof any l Moton'iseornmnicnted fmthe ninchine from the driving-sheflfK'to they shaft oi'` roller J by means of yn.
